I am a licensed radio amateur ("ham") with the call sign DJ1YFK. I love Morse Code (CW); the faster the better.
To foster its usage and to preserve it for the future, I developed Learn CW Online (lcwo.net), a web-based Morse course and practice tool with a community of more than fourty thousand users — world-wide, growing day by day.
In the ham radio section of my website you'll find more information about my activities and some radio related software that I wrote (YFKlog, qrq, ebook2cw, ...).
During the first semesters of my studies of electrical engineering at Dresden University of Technology (2003 - 2005), I transcribed some lecture notes in LaTeX. Almost a decade later, they are still used by many students. Everything is available as PDFs and LaTeX sources, licensed under the terms of the CC-BY.
